It's posted all over the place that 10GB isn't enough and that if you need room, get the mini or use the package selection and unselect a bunch of packages. It's really going to be pure misery working with 10GB with the DVD, you are going to have all sorts of problems cause it has nothing to work with.

If it ran find on livedvd than it will work on harddrive, you may have to run the accel-manager and edit the xorg.conf. You can even copy over the xorg.conf from the livedvd session to your hard drive.
